I would like to add a sentence in the signature to all my emails (I'd prefer not to use Word), using Outlook. This would give the current state of my virus defs. To do so, I need to check the file date for one of Norton's files and (ideally) subtract 1 day from the date. I would then use that date in a sentence.

Has anyone any idea how I would do this? I would use Word if I have to.

Thanks
